Mac Miller sat down with Fuse before his set this weekend at Bonnaroo to catch up on a couple things he has going on in 2012. First, he talks about his appearance on Justin Bieber's "Boyfriend (Remix)" with 2 Chainz and Asher Roth, saying that his Twitter account went crazier than ever after it dropped, and he gained 40,000 followers in one hour. He also talks about linking up with Pharrell (he doesn't remember how they initially met), and their upcoming collaborative EP Pink Slime, saying that Pharrell is a true believer in his creative potential. Watch above.
